使用Universal-Image-Downloader下载图像时出现SecurityException

Question

在我的应用程序上，我使用通用的图像下载器BaseImageDownloader类同步加载画廊的内容。对于来自Imageloader.getInstance（）。loadImage异步函数的相同内容，它不会给出任何安全异常并按原样加载图像，但是当我尝试使用BaseImageDownloader同步下载它（而且Imageloader.getInstance（）。loadImage（）相同），我得到了此安全异常

我也搜索了代码，但您对配置或其他地方没有任何许可，这是什么原因？

public Bitmap decodeSampledBitmapFromStream(String path, int reqWidth, int reqHeight) throws IOException {
        BaseImageDownloader downloader = new BaseImageDownloader(getApplicationContext());
        InputStream stream = downloader.getStream(path, null);
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(stream, new Rect(-1,-1,-1,-1), options);
        stream.close();
        options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

        options.inJustDecodeBounds = false;
        stream = downloader.getStream(path, null);
        Bitmap bitmap = BitmapFactory.decodeStream(stream, new Rect(-1,-1,-1,-1), options);
        stream.close();
        return bitmap;
    }

我向mainfest添加了权限，并且它起作用了。但是我不知道没有它，UIL是如何制造的？

<uses-permission android:name="com.google.android.gallery3d.permission.GALLERY_PROVIDER"/>
